An increment core-based, laboratory method was used to measure tissue-level respiration under controlled temperature (termed respiratory potential) of eleven tree species from three age classes. Respiratory potential was ...

Copper is an excellent biocide which has a long history of usage for protecting wood from deterioration, but some organisms have developed tolerance for this chemical. Copper tolerance among wood decay fungi is a poorly ...

The overall goal of this study was to evaluate an alternative to
traditional wood framed shear wall construction. This study introduced the
innovative idea of using a water and seismic damage resistant, wood-concrete-
...

Phytophthora ramorum is a plant pathogen that was accidentally introduced to the United States. This invasive microorganism has killed over a million trees in California and Oregon, and continues to spread to new areas. ...

New species introductions have been associated with the movement of
people for thousands of years. For instance, horses were introduced into North
America by Spanish explorers, while pigs were introduced by the Polynes ...

There is a continual interest in developing robust, flexible, durable,
lightweight, waterborne polymer barrier coatings which are increasingly resistant
towards both chemical warfare agents as well as an ever growing n ...

We studied the feasibility of using end-grain characteristics to match individual boards and cants back to their parent Douglas-fir (Pseudotsuga menziesii) logs. After reviewing marking/reading and biometric automated id ...

Logging and forest thinning operations generate large amounts of residues in the
form of small trees, branches and foliage that are usually left on the ground to decay or
are burned. These resources are readily availab ...

The objective of this study was to develop and validate practical modeling
methods for investigating load paths and system behavior in a realistic, light-frame wood
structure. The modeling methods were validated agains ...

Existing pressure sensitive adhesives (PSAs) are mostly based on petrochemicals. In this study, a novel PSA based on a renewable material, methyl oleate, was prepared and characterized. Methyl oleate was first epoxidiz ...

Sandwich composites are typically produced from two high strength facings bonded to a lower strength, lightweight core. Sandwich design has proven to be efficient for applications demanding high strength and low weight. ...

The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objecti ...

Every wood anatomist knows that the wood near the center of a tree (juvenile wood) differs from the wood laid down at some distance from the pith (mature wood), and that the wood produced during the spring (earlywood) di ...

Wildfire prevention operations like forest thinning and forest fuel removal result in large volumes of woody biomass available for utilization. In 2007 alone, the US federal government spent nearly $2 billion to fight fo ...

The timber shortage in the Pacific Northwest is forcing sawmill owners to
improve the competitiveness of their harvesting and processing
operations. A computer simulation and financial statement analysis were
used to ...

Since 2004 there have been multiple devastating tsunamis around the globe triggered by large magnitude earthquakes; with the most recent being the Tohoku, Japan tsunami in March 2011. These tsunamis have caused significa ...
